(They do not prove the existence of such toxemia, since approximately corresponding lead concentrations may be found in the absence of symptoms. normal lead concentrations in the brain range from 0.01 to 3.09 milligrams per 100 grams, in our experience; elevated concentrations without of cerebral or other lead intoxication range up to O.35 milligrams per 100 grams in several cases on which we have adequate data. ) In a series of cases of encephalopathy due to absorption of tetraethyl lead, the lead concentrations in the brain ranged from 0.46 to I.65 milligrams per 100 grams, while in encephalopathy due to inorganic lead in the case of children.

(They do not prove the existence of such toxemia, since approximately corresponding lead concentrations may be found in the absence of symptoms. normal lead concentrations in the brain range from 0.01 to S-.09 milligrams per 100 grams, in our experience; elevated concentrations without signs of cerebral or other lead intoxication range up to 0.55 milligrams per 100 grams in several cases on which ve have adequate data. ) In a series of cases of encephalopathy due to absorption of tetraethyl lead, the lead concentrations in the brain ranged from 0.46 to I.65 milligrams per 100 grams, while in encephalopathy due to inorganic lead in the case of children, these concentrations ranged from 0.94 to 0.58 milligrams per 100 grams.

Perhaps one of the most dramatic cases of the effect of additives is the well known example of tetraethyl lead.

The fourth paragraph makes the categorical statement that lead poisoning from anti-knock gasoline containing tetraethyl lead is one of the most serious forms.
